OSKAR SELID AND KRISTIAN PETTERSEN, OF SARPSBORG, NORWAY.

ELECTRIC HEAT-STORING- APPARATUS.

Specification of Letters Patent.

Patented July 29, 1919.

Application filed April 28, 1919. Serial No. 293,287.

To all whom it may concern:

Be it known that we, OSKAR SELID and KRISTIAN PETTERSEN, both of Sarpsborg, in the Kingdom of Norway, have invented certain new and useful Improvements in Electric Heat- Storing Apparatus; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to electrlc heat storing apparatuses of the kind, where the-heat is accumulated in a storing body placed in a. chamber formed in a body of heat insulating material. The invention particularly relates to electric heat storing kitchen ranges of the kind, in which a storing body of metal is placed in a caseformed of insulating material, said case or vessel also comprising other rooms or chambers adapted to be heated more or less by transmission of heat from the heat storing body.

The invention consists in arranging etween the heat storing body and the several chambers in the range heat transferring channels controlled by valves in such a mannor that more or less heat may be transferred to the several chambers. The heat transferring channels may consist in air filled channels which may be opened and closed by means of a valve, or the transfer of the heat may be effected by conductors formed of good heat conducting material, in which case it may be controlled by means of slide valves or disks of conducting or insulating material.

Preferably the several chambers may be so disposed with regard to the heat storing body that a small valve mechanism may be utilized for conducting the heat to one chamber or the other, said valve being then constructed as a multiple way cock with section of a heat storing apparatus embodying the invention.

Fig. 2 is a detail section showing the valve in another position from that shown in Fig. 1.

Fig. 3 is a similar detail section with the valve in a third position, and

Fig. 1 is a vertical section of the valve.

1 is the heat storing body, which is placed in a case 2, formed of a suitable heat insulating-material. In the case 2 there is also located chambers 3, 4, which are heated more or less effectively from the heat storing body. Between the heat storing body 1 and the chambers 3 and 4 there is arranged channels 5, 6, 7 which communicate with a chamber 8, inclosing a rotatable cylinder valve 9. Said valve 9 may be provided with a passage 10, which as illustrated on Figs. 1, 2 and 3, is adapted to connect the heat storing body 1 with either of the chambers 3 or 4 or cut it off from both of these chambers.

The channels 5, 6, 7 and 10 may be open, or may, as above stated, consist of conductors of good heat conducting material.

Claims:

1. In an electrically heated range or the like, a heat accumulating body, a case formed of insulating material inclosing said body, a plurality of heating chambers located in said case, a heat transferring channel between the heat accumulating body and each of said heating chambers, and valve controlling said channels for regulating the supply of heat from the heat accumulating body to the several chambers.

2. In an electrically heated range or the like, a heat accumulating body, a case formed of insulating material inclosing said body, a plurality of heating chambers located in said case, a heat transferring channel between the heat accumulating body and each of said heating chambers, and a multiple way valve for directing the heat from the heat accumulating body to any of the said heating chambers;

In testimony that we claim the foregoing as our invention, we have signed our names in presence of twosubscribing witnesses.
